Woo where to begin.
When I was a preteen I would do OTC highs (DXM, benadryl, alcohol, etc).
As I got older I tried out psychedelics:
Cannabis/Hashish (not exactly a psychedelic to me but eh, I love it and use it every day)
Mushrooms (good experience until I started watching TV)
LSD (never had a bad time)
MDA/MDMA (never had a bad experience)
Ketamine (great for pain relief when I ran out of pain killers and dope)
PCP (will never do it again)
I grew out of psychedelics and into stimulants:
I first learned to make MCAT as I had tried Khat leaves and liked the effect. When that started not doing it for me I started making my own crank and from there started cooking 4-MAR because of the MDMA like effects and it felt cleaner as far as short term use went). Got tired of that crap within a few years and started growing my own coca plants and started extracting my own cocaine. From there I would rock it up because it was less messy. I remember spilling a 1/2 a spoon on my carpet and trying to get down and rail it. Rocks could fall all they want. The high was short and crappy though so I stopped smoking the freebase and went back to simply doing lines of the pure snow. Better effect anyway, just had to be a little more careful.
Started using pharms (adderall, concerta/ritalin, phentermine) whenever I needed them (mostly for focus and easing withdrawals)
I eventually broke the spell of stimulant abuse (lost tons of weight and staying up for days was no longer fun).
I got into pain killers a few years later (in my late 20's) when I cut open my hand and got prescribed oxys. From there I started scoring hydros, oxys, etc. They started getting to expensive to I switched to heroin and opium/morphine.
I would use various benzos to ease the comedowns (xanax, valium, ativan, and a few others). Not fun blacking out so I stopped using them.
I have tried various research chemicals (mephedrone, various 2C substances, MDPV, and bk-MDMA)
I have tried a lot of drugs in my days in various ways. Only way I have not done a drug was anally and that is because I refuse to let anything near that exit except some tissue. It is not an input and it never will be. I have smoked, snorted, IV'ed, IM'ed, took orally, etc).
Now that I am older (40's) I can't believe how much of my life I wasted. All the overdoses, all the danger. It was a good learning experience though. Now I only stick to cannabis. I have never really had a problem with addiction. For the most part I could use and stop as I wanted. Most are not as lucky as me.
